MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 264,734, dated September 19, 1882,

Application filed March 17, 1882. (No model.)

To all whom it may concern:

Be it known that I, LEWIS N. MERRIMAN, a citizen of the United States, residing at Dixon, in the county of Lee and State of Illinois, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification, reference beinghad therein tothe accompanyingdrawings.

My invention relates to devices for trans mitting the motion of wind-wheel shafts to attached machinery, and for other purposes to which it maybe found adapted; and it consists in the construction and arrangement of its several parts, as will be hereinafter fully set forth, and pointed out in the claim.

In the drawings, Figure l is a view in perspective of the link and journal-boxes; Fig. 2, a side elevation of the device applied to a windmill, and Fig.3 a section of the upper portion of the device.

A A are the ,supporting-stanchions, having braces a a, as shown. To the top of the stanchions is secured the flat disk a upon which rest the fan-shait a and transmitting device, hereinafter to be described. Operating in an annular groove in the disk at is the ring a having secured to its sides the bearings a in which is journaled the shaft 0., as shown. The ring a is held in position by the keeper M, which is bolted to the disk a as shown. Placed around the shaft a are the circular shoulders b b, between which is the intermediate shoulder, 11. Iivoted between the shoulders band 12' upon the pivot-pins b, at

points at right angles to each other from the center of the shaft, are the boxes b They are constructed in separate parts and secured together by stud-bolts or other suitable means.

0 G are the connecting-rods. To their upper end are securt d the elongated links 0 c, which have upright pistons c c projecting from their upper ends and operating through ajournal-arch, 0 which is bolted to the disk a as shown. Extending horizontally through boxes in the sides of the linksa are actuatingshafts 0 They are secured through the journal-boxes o The shafts 0 convert the re volving motion of the shoulders 11 b and circular motion of the boxes b and transmit it to the links 0, imparting to them a vertical movement. In operatingthe shafts 0 remain stationary in the boxes b but slide horizontally in the boxes in the sides of the links 0. When in position. the links 0 embrace the shoulders I), as shown. Secured to the braces to are the sills c e, upon which is journaled the shaftf, which has keyed to its outer end the pulley g. The connecting-rods G O,which 0on nect the shafts, are divided into upper sections, 6 f, and lower sections,e f as shown. Formed in the section 6 is the piston g, which operates through a ball-andsocket joint, as shown, upon the end of the section f and througha guide-hole in the brace at. Its lower end' forms a balland-socket'connection, 6 with the section 6 Upon the lower end of the section f is formed a ball, which has a vertical hole running through it, to permit the passage of the section 0, and it is embraced by a' socket, 9 upon the upper end of the piston g, which operates through a guide in the brace a, as shown. Upon eitlierend of the shaft to is the wind-wheel, (not shown,) and upon the pulley g is placed a belt to connect it with the machinery to be driven. A crank may be used instead of the pulley, if desired.

In operation the actuating-shafts c slide horizontally in the links and transmit to them the motion received from the revolving shoulders b b and shaft a.

By this construction and arrangement of the connecting-rods G O, shoulders I) b and b,

and boxes b upon the shafts c andf, I secure a device for transmitting and changing the direction of motion, in the operation of which there can be no dead-center upon either shaft, in which there is but a small amount of friction and of simple economical construction. As will be seen, the rods 0 C have no lateral motion, as is the casein connecting-rods of ordinary construction and operation. The arch c prevents lateral strains upon the links, andconsequent binding of the actuatingshaft c in the link-boxes.

What I claim is- In a mechanical movement, the combination, with the revolving disk a the vertical journal-arch c ,'secured to said disk, the connecting-rods O, and elongated links 0, provided with pistons 0, operating through boxes in the top of the journal-arch c of the shaft a, I In testimony whereof I hereby affix my sigjournalecl upon the disk aiprovided with oircul nature in presence of two Witnesses. lar shoulders I) b b and boxes b through which are secured horizontal bars 0 adapted to LEWIS MERRIMAN' slide through suitable apertures in the sides I Witnesses:

of the links c, all arranged to operate suhstan- LEWIS MERRIMAN, tially as shown, and for the purposes set forth. RODERIO H. BOSWORTH.
